Michael Wood,
Thanks to your proposition I was able to intercept the size information
sent to
windows by samba using the dfree command and have displayed the proper
size.
The only thing I did was adding
dfree command = /usr/local/samba/bin/dfree
and in the dfree script I put :
df $1 | tail -1 | awk '{printf "%.0f %.0f", $(NF-4),$(NF-2)}'
And suddently windows was able to calculate the proper size of my ceph
partition.
Thank you again that helped me alot.

I tryed to lie about the block size, but unfortunatly windows blocksize buffer
is coded into 2 bytes (short int). so the size upper to that like Ceph that has
1MB of block size will not be handled the proper way.
My guess (it is just an assuption) is that samba can detect who connects to it and if it
is a true windows workstation /server then the samba lures the count by multiplying the
amount of blocks by 1MB / (blocksize from 1K to 64K). In order to allow people to play
with the samba "block size = " parameter in the smb.conf.
Well, my suggestion is just a guess. Did you try supplying your own
script for the "dfree command"?
I have not tried it myself.

Dear developement team,
I want to share a massive storage casted with Ceph by samba with windows
workstations.
All works well. My problem so is that in windows the ceph storage size
statistics are wrong. Instead of seeing a 44TB hard drive I see a 176GB hard
drive.
Under linux that issue doesn't show. The size are properly reported.
I investigated around and it seems that the problem belongs in the unability
for windows
to treat blocksize over 65k and by default the block size is 4K.
Don't know how you can solve that issue but I really need to get that
working right.
I don't know if this will help, but it might be worth a try. There's
a "dfree command" option that specifies a command to run to get the
free disk space:
http://www.samba.org/samba/docs/man/manpages-3/smb.conf.5.html#DFREECOMMAND
So if Windows doesn't like the block size, maybe you could lie about
the block size and then calculate the number of blocks based on the
fake block size.
There's also a "max disk size" option that may or may not make any difference:
